Bracketing / HDR Script with continuous mode

I think a script would be the best way to do it. Do you want the script to do a single HDR photo or HDR time lapse?

Right now, I thought a about script to do a single HDR photo.HDR and time lapse, you did this before?Only requirement it should be run in continuous mode. There is a script above which also works with a histogram but it did not run in continuous mode.

My idea for HDR would be to start with an ETTR photo. That is, a photo that is exposed as brightly as possible without "blowing" any pixels. I see no need for any bracketed exposures darker than that, do you? Starting from the ETTR photo, the script would then take additonal exposures of around +2, +4, +6 ev with the actual ev changes set by script parameters. The HDR program, Photomatix, recommends 2 ev between exposures.

Yes, but how you get a ETTR photo from start?I thought you have to make one shoot, to get data from RAW meter or? If this photo is overexposed you should go down with -EV steps to come to ETTR. And then you can go up with +EV steps from first picture, right?

That sounds like a good plan. I did something like that in my solar eclipse script.

I finished the modifications to CHDK that I'll need for my scripts. They should be backwards compatible, so you can install my CHDK builds on all your cameras if you want to test it out. Here's a link with all the camera builds:

I have download CHDK-g1x-101a-1.5.0-4917 and updated. But I don’t see correct version info. But ‘TestRwop’ works…

From the July build date, it looks like you still have the first CHDK version I posted for you. Check the "modified" date of DISKBOOT.BIN on your SD card and make sure it is September. Try downloading the new CHDK version again. Google Drive is pretty confusing for just downloading something. There's a button at the upper right to switch to List view, which is a little easier to figure out.

I added a count of underexposed pictures to rawop.meter, and attached the new TestRwop.lua, and a CHDK version for your G1X if you have trouble with Google Drive. The new TestRwop will throw a "nil" error if you don't have the right CHDK version.

OK, thanks for checking that out. For some reason, the dates and version info is wrong on your camera, but since the script works, you must have the right CHDK build. Let's not worry about it for now. Thanks for testing.

A few years ago, Waterwingz showed me how to modify the splash screen to show "Lapser" instead of CHDK. That method doesn't seem to work any more. Is there a way to do that now?
